Power supply

An internal rechargeable LiPo battery is used to power the vibration meter. With a fully charged
battery and depending on the display brightness, a battery life of approx. 15 ... 20 h is possible.
The battery is charged via the USB port at the bottom of the meter, using a USB charger. The
charging process can be shortened by switching off the meter while charging.
The current battery level is displayed in the status bar in the top right corner of the screen. If the
battery charge is insufficient for proper operation of the device, the device automatically powers
off and the display below is shown.

Preparation

Connect the sensor with the spiral cable to the vibration meter before turning it on and connect

displayed instead of the reading in the different measuring functions and the corresponding
memory functions are deactivated. This indication also helps diagnosing cable breakage.
